This is a discussion on Lightened Flywheels within the JC Racing forums, part of the Vendors category; Originally Posted by jc250r31 I'll fix it to make it as clear as possible. Yea you better...or else you'll have another 2 page "issue" on ...
Updated pricing due to being able to get my hands on flywheels no easier and cheaper. Passing the savings along. Pricing is now the same as the Ruckus.
Updated first post with some new info.
Wondering about this problem, can someone for JC racing comment, thanks

I got my reduced weight flywheel and oil spinner installed. I was wondering who else has installed these parts? Please chime in if you have first hand experience doing this.
What I have found is it dose rev quicker and gets up to speed quicker. I can certainly tell the torque off the line has been reduced. without that mass Its very hard to wheelie. In fact I'm noticing the clutch feels sloppy now after a 15 min ride. It grabs less efficient than it did before. I'm concerned I might need HD clutch plates.
Overall I like the mod and enjoy the quickness up to speed but I'm kind of on the fence about keeping it installed if it kills the clutch. Maybe I'll just do the flywheel and add some weight back with the stock spinner.
For reference my mods are full exhaust, K&N on intake and lightened flywheel and spinner.
This is what I posted on the other Grom website
wondering if you changed from dino oil to full synthetic oil and that might be part of the problem. Just trying to figure out why you can't do wheelies the HP should be the same and the only thing you did was reduce internal mass weight, anyway would be interesting to know what caused the problem.
He will probably need to lower his gearing some with a sprocket change if he wants to do wheelies. He is probably killing the clutch more trying to get the front wheel up which in turn is making it feel sloppy. With the reduced mass it will make it a little more difficult to get the front wheel up than before but a sprocket change will fix that very easily.
What's the Grom stock flywheel weight and average lightened flywheel weight? Is it surprising/any reason no one has made a new core lightweight aluminum flywheel?
Any more with this mod, and feedback?
